The Effect of Dexmedetomidine Pretreatment on the Median Effective Bolus Dose of Propofol for Facilitating Laryngeal Mask Airway Insertion

Background We designed this study to investigate the effect of dexmedetomidine (1 μg/kg) pretreatment on the median effective dose (ED50) of propofol for facilitating successful laryngeal mask airway (LMA) insertion compared to propofol alone.
